快速成形技术是综合利用CAD技术、数控技术、激光加工技术和材料技术实现从零件设计到三维实体原型制造一体化的系统技术。它采用软件离散一材料堆积的原理实现零件的成形。

Rapid prototyping technology is a system technology that comprehensively utilizes CAD technology, CNC technology, laser processing technology, and material technology to achieve integration from part design to 3D solid prototype manufacturing. It adopts the principle of software discretization and material stacking to achieve the forming of parts.

具体过程如下：利用高性能的CAD软件设计出零件的三维曲面或实体模型；再根据工艺要求，按照一定的厚度在Z向(或其它方向)对生成的CAD模型进行切面分层，生成各个棱面的三维平面信息；然后对层面信息进行工艺处理，选择加工参数，系统自动生成刀具移动轨迹和数控加工代码；再对加工过程进行仿真，确认数控代码的正确性；然后利用数控装置精确控制激光束或其它工具的运动，在当前工作层(三维)上采用轮廓扫描，加工出适当的截面形状；再铺上一层新的成形材料，进行下一次的加工，直整个零件加工完毕?？梢钥闯?，快速成形技术是个由三维转换成二维(软件离散化)，再由二维到三维(材料堆积)的工作过程。

The specific process is as follows: using high-performance CAD software to design three-dimensional surfaces or solid models of parts; According to the process requirements, the generated CAD model is sliced and layered in the Z direction (or other directions) according to a certain thickness, generating three-dimensional plane information for each edge surface; Then, process the layer information, select machining parameters, and the system automatically generates the tool movement trajectory and CNC machining code; Simulate the machining process again to confirm the correctness of the CNC code; Then, using CNC devices to precisely control the movement of laser beams or other tools, contour scanning is used on the current working layer (3D) to process appropriate cross-sectional shapes; Lay another layer of new forming material and proceed with the next processing until the entire part is processed. It can be seen that rapid prototyping technology is a work process that transforms from three-dimensional to two-dimensional (software discretization), and then from two-dimensional to three-dimensional (material stacking).

快速原型法不仅可用于原始设计中快速生成零件的实物，也可用来快速复制实物(包括放大、缩小、修改和复制)。其工作原理是，用三维数字化仪采集三维实物信息，在计算机中还原生成实物的三维模型，必要时用三维CAD软件进行修改和缩放，然后进行三维离散化并送到成型机生成实

The rapid prototyping method can not only be used to quickly generate physical parts in the original design, but also to quickly replicate physical objects (including zooming in, zooming out, modifying, and copying). The working principle is to collect three-dimensional physical information using a 3D digitizer, restore the generated three-dimensional model of the physical object in the computer, modify and scale it with 3D CAD software if necessary, then discretize it in three-dimensional and send it to the forming machine to generate the physical object
